Portfolio selection using behavioral models
Nell'ambito dei problemi di scelta in condizioni di rischio introduciamo un nuovo modello comportamentale e implementiamo un'analisi empirica basata sul confronto con il classico approccio della Teoria del Prospetto. L'applicazione di questi modelli è validata nella selezione di portafoglio attraverso tre modelli di portafoglio tradizionali utilizzati come riferimento (portafoglio a varianza minima, portafoglio a deviazione mediana assoluta e portafoglio equamente ponderato). L'obiettivo di questo lavoro di ricerca è quello di incorporare la percezione del rischio degli investitori nelle scelte dei portafogli ottimali. Proponiamo un'analisi out-of-sample di quattro indici azionari per dimostrare la superiorità dei modelli comportamentali di selezione di portafoglio rispetto a quelli tradizionali.

Mistakes, Errors and Failures across Cultures
This volume provides comprehensible, strength-based perspectives on contemporary research and practice related to navigating mistakes, errors and failures across cultures. It addresses these concepts across cultural contexts and explores any or all of these three concepts from a positive psychology or positive organisational perspective, highlighting their potential as resources. The volume further discusses the consequences of errors and failures at individual, organisational and societal levels, ranging from severe personal problems to organisational and collective crises, perspectives how those can be turned into opportunities for contingent and sustainable improvement processes. The book shows that there are significant cultural differences in the understanding, interpretation and handling of errors and failures. This volume provides practical guidance for transcultural understanding of mistakes, errors and failure through new models, ideas for self-reflection, therapeutic and counselling interventions and organisational change management processes. This book is a must for researchers and practitioners working on mistakes, errors and failures across cultures and disciplines!
Competition Culture and Corporate Finance
This book introduces a measure of firms’ competition culture based on a textual analysis and natural language processing (NPL) of firms’ 10-K filings. Using this measure, the book explores the relationship between competition culture and various phenomena in corporate finance, specifically, institutional ownership structure, stock return performance, idiosyncratic stock price crash risk, meeting/beating analysts’ earnings expectations, and earnings management activity, for a large sample of US-based financial and non-financial firms. In particular, the book provides evidence that transient institutional ownership intensifies firms’ competition culture, while dedicated institutional o...
Fractional Volterra Integral Equations: A Neural Network Approach
Il Calcolo Frazionario ha recentemente guadagnato un crescente interesse nella letteratura economica e finanziaria. Per quanto riguarda i modelli economici, quelli di crescita sono stati modellati utilizzando una rappresentazione tramite derivate frazionarie. Questo tipo di equazioni non consente soluzioni in forma chiusa e quindi è necessario ricorrere a metodi numerici appropriati per ottenere approssimazioni accurate delle soluzioni. Per questo motivo, in questo contributo, proponiamo un approccio basato sulle cosiddette Physics Informed Neural Network per risolvere le equazioni integrali di Volterra di ordine frazionario. Alcuni esperimenti numerici mostrano l’accuratezza dell’algoritmo suggerito.
Cooperative Banking: Innovations and Developments
The book describes the current role and rationale of co-operative banking and examines features such as governance, consolidation, outsourcing, shareholder value and rating evaluation. It then analyses the likely impact on the strategic, organisational and operative model of cooperative banks.
Stability of Entropic Risk Measures
L'errore di stima è un tema cruciale che riguarda la selezione di portafoglio. La maggior parte degli studi concerne le misure di rischio più famose, quali la varianza, il Mean Absolute Deviation (MAD), e il Conditional Value-at-Risk (CVaR). D'altro canto, al momento, non sembrano esserci studi riguardanti la stabilità di misure di rischio entropiche quali l'Entropic Value-at-Risk (EVaR) e il Relativistic Value-at-Risk (RLVaR). Utilizzando dati sia simulati sia storici, abbiamo trovato che, mentre l'EVaR e il CVaR manifestano un profilo di stabilità simile, il RLVaR è molto più sensibile al rumore.

Internationalization of Banks
This book reviews banking internationalization by considering the new paradigms of globalization. The author primarily analyses why and how banks internationalize through equity deals, and the effect of regulation and market integration on the formation of deals, which allows authorities to manage the banking structure. This is a unique work that describes the relevance of the ownership model and cultural features of the partners and the key factors that help in choosing the market in which the banks bring activities abroad. The book addresses market characteristics, and new scenarios that should impact banks’ internationalization strategies and ability to achieve success in deals that capture the attention of both researchers and practitioners.
Contemporary Issues in Financial Institutions and Markets
This book brings together academic work on contemporary issues in financial institutions and markets. The general theme is designed to allow for a wide range of topics, covering the diverse nature of academic enquiry in banking and finance. The contributions thus address a broad spectrum of contemporary issues including bank diversification and securitization activities; bank regulatory reforms and competition; the performance of mutual funds and alternative asset classes; role of liquidity in price discovery for credit derivatives; and the existence of the compass rose pattern within option contracts market. This book was originally published as a special issue of The European Journal of Finance.

The section on machine learning applications then examines healthcare analytics, insur...
Classical Economics, Keynes and Money
Classical Economics, Keynes and Money casts new light on an approach to economic theory and policy that combines the modern classical theory of prices and income distribution with a Keynesian analysis of money and finance. Structured in four parts, the work considers issues within classical economics, monetary economics, Keynesian and post-Keynesian Economics, rationality and economic methodology. These themes are all central to the work of Carlo Panico, and the chapters both reflect on and build on his key contributions to the field. This collection is of interest to advanced students and researchers in the history of economic thought, monetary theory, financial economics and heterodox economics.
